Calcium
Calcium is an important nutrient that plays a role in normal body functions. This guide explains what it does, common food sources, what can affect intake, and how tracking your diet can help you understand your overall nutrient intake.
Recommended intake varies by age, sex, and life stage. Tracking what you actually eat can help you understand your overall dietary intake over time.
What Calcium does
Calcium plays a role in:
- building and maintaining bones and teeth
- supporting muscle movement
- helping nerves carry messages through the body
- contributing to blood vessel function and hormone release
Calcium intake
Intake targets vary across life stages. Age, sex, eating patterns, food variety, and day-to-day routines can all influence how much calcium appears in a person’s diet.
Tracking can help you compare your usual food pattern with the foods that commonly provide calcium.
Common food sources of Calcium
Food sources of Calcium may include:
- milk, yogurt, and cheese
- calcium-fortified plant milks or cereals
- canned sardines or salmon with bones
- kale, broccoli, and bok choy
- calcium-set tofu
The amount can vary depending on the food, serving size, preparation method, and brand.
What can affect Calcium intake
A person’s intake may vary due to factors such as:
- food preferences and usual food choices
- restricted diets or low intake of dairy or fortified foods
- appetite changes or small meal sizes
- digestive tolerance and limited food variety
- lifestyle habits and meal routines
Why intake may be lower in some people
Some people may find it harder to get enough Calcium from food alone because of:
- low intake of dairy foods, fortified foods, fish with bones, or calcium-rich plant foods
- limited meal variety over time
- poor tolerance of some common calcium food sources
- changing appetite or eating patterns
Dietary intake can vary a lot from one person to another. This page is about food intake and tracking, not diagnosis or treatment.
